Tasty Morsels of EM 033 – Melanoma recognition

27 Sep

I keep a little, ever-expanding note on my phone where I jot down little morsels of goodness that I pick up while listening to or reading one of the many excellent sites/podcasts in the useful resource section. They’re useful in a kind of “board review” way. I tend to skip the really basic stuff and try and focus on what I didn’t know.

I’ll try and transfer them here for your enlightenment.

I ended up browsing this on uptodate one day. Still not sure why…

ABCDE for melanoma

  • Asymmetry (if a lesion is bisected, one half is not identical to the other half)

  • Border irregularities

  • Color variegation (brown, red, black or blue/gray, and white)

  • Diameter ≥6 mm

  • Evolving: a lesion that is changing in size, shape, or color, or a new lesion

Prognosis is linked to thickness of tumour. Stage 1 has a great 92% 10yr survival

The ugly duckling sign

  • Most naevi share characteristics that make them look like other nearby naevi. If there’s one that really stands out then think melanoma
